**XATTR Problem**
If I download and run the Axon.ivy Designer with Safari on my High Sierra the Designer does not start. The unzipped 'Axon.ivy Designer.app' can not be booted: (fails with an Eclipse window stating that the Engine boot failed -> See /logs
Occasionally a dialog could appear that warn the user about the app verification: `Designer is damaged`

Cause:
- restriction that downloaded files have see xattr Axon.ivy Designer.app: https://derflounder.wordpress.com/2012/11/20/clearing-the-quarantine-extended-attribute-from-downloaded-applications/
Solution:
- Remove XATTRS with this command in a terminal: `sudo xattr -r -d com.apple.quarantine Axon.ivy Designer.app`
Afterwards the Designer boots like a charm...
----------
**Gray Process Editor**
The Designers shows only a grayed out editing window when I open a new process with the Process Editor.
Work-Around:
- force a re-drawing of your editing content with a Zoom+IN/Zoom+OUT keyboard combination: (Apple+/Apple-)
----------
**Designer boots with gray empty front-end**
The Designers boots but shows only a gray empty window.
Cause:
- Java Runtime Environment (JRE) is not compatible. The ivy version 7.3 only runs with a Java 1.8 JRE. Sprint releases of 7.4 should already run with the Java 11 (LTS).
Work-Around:
- Install a JAVA 1.8 11 JRE: e.g. from AdoptopenJDK: https://adoptopenjdk.net/releases.html#x64_mac
- Finder: Right Click on AxonIvyDesigner > Show Package Contents > Open the file `Axon.ivy Designer.app/Contents/Info.plist`
- Define the `-VM` argument under the `<key>Eclipse</key>` and point it to compatible Java installation. As it is shown in the out-commented section just below.
- Verify by rebooting the designer and optionally checking the booted java version in a terminal: `ps -e | grep java`
